hi, it is really quiet over here. when you'd like to have your AspireOne just as quiet there is a small part of the kernel that does the job -- acerhdf (see http://www.piie.net/index.php?section=acerhdf). I encountered this piece of software looking at the terminal output from update -y... Code: $ su - # echo -n "enabled" > /sys/class/thermal/thermal_zone0/mode and your fan wil only take off when needed. the only post about implementing acerhdf I found was for *buntu but it didn't work with Fedora 16 LXDE. so I emailed Peter, the author of acerhdf. he gave following reply you could do following line as root: Code: echo "options acerhdf verbose=0 fanon=62000 fanoff=52000 interval=10 kernelmode=1" >> /etc/modprobe.d/acerhdf.conf then on the next start, acerhdf should automatically take over fan control.
